Climate change could worsen African "megadroughts"

The recent decades-long drought that killed 100,000 people in Africa's Sahel may be a small foretaste of monstrous "megadroughts" that could grip the region as global climate change worsens, scientists reported on Thursday.

New study warns damage to forests from climate change could cost the planet its major keeper of greenhouse gases
April 17, 2009 06:59 AM - The Collaborative Partnership on Forests

The critical role of forests as massive "sinks" for absorbing greenhouse gases is "at risk of being lost entirely" to climate change-induced environmental stresses that threaten to damage and even decimate forests worldwide, according to a new report released today. The report will be formally presented at the next session of the United Nations Forum on Forests (UNFF) taking place 20 April-1 May 2009 at the UN Headquarters in New York City.

Third-World Stove Soot Is Target in Climate Fight

"It's hard to believe that this is what’s melting the glaciers," said Dr. Veerabhadran Ramanathan, one of the world’s leading climate scientists, as he weaved through a warren of mud brick huts, each containing a mud cookstove pouring soot into the atmosphere.

California Utility Considering Space-based Solar Arrangement
April 15, 2009 04:03 PM - Environmental Leader

When procuring just about anything, it makes sense to get as close to the source as possible. That’s the idea behind an ambitious plan to harvest solar energy from outer space, then beam the electricity back to Earth.

Midwestern ethanol plants use much less water than western plants, U of Minnesota study says

Ethanol production in Minnesota and Iowa uses far less water overall than similar processes in states where water is less plentiful, a new University of Minnesota study shows. The study, which will be published in the April 15 edition of the journal Environmental Science and Technology, is the first to compare water use in corn-ethanol production on a state-by-state basis. The authors used agricultural and geologic data from 2006-2008 to develop a ratio showing how much irrigated water was used to grow and harvest the corn and to process it at ethanol plants. Among the major ethanol-producing states, Iowa uses the least water, with about six gallons of water used for each gallon of ethanol. Minnesota, which in 2007 produced roughly a third as much ethanol as Iowa, uses about 19 gallons of water per ethanol gallon.

EPA Publishes Annual U.S. Greenhouse Gas Inventory Report
April 15, 2009 03:15 PM - U.S. Environmental Protection Agency

The U.S. Environmental Protection Agency has released the national greenhouse gas inventory, which finds that overall emissions during 2007 increased by 1.4 percent from the previous year. The report, Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2007, is the latest annual report that the United States has submitted to the Secretariat of the United Nations Framework Convention on Climate Change, which sets an overall framework for intergovernmental efforts to tackle the challenge posed by climate change.

EPA Evaluates Ocean Acidification as a Threat to Water Quality Under Clean Water Act

The United States Environmental Protection Agency announced steps to protect U.S. waters from the threat of ocean acidification under the Clean Water Act. Today, EPA issued a notice of data availability to be published in the Federal Register that calls for information and data on ocean acidification that the agency will use to evaluate water-quality criteria under the Clean Water Act. The notice responded to a formal petition and threatened litigation from the Center for Biological Diversity that sought to compel the agency to impose stricter pH criteria for ocean water quality and publish guidance to help states protect American waters from ocean acidification. EPA's notice marks the first time that the Clean Water Act will be invoked by the agency to address ocean acidification.
